I know signature campagns exists on this forum for very log time . I was wondering , do they really help to promote ICO , i know they spend a lot of money to pay bitcointalk members to wear their singatures and make posts . Do they really make profit out of this ?
Signature campaign is still one of the very effective promotion for ICOs. There are many potential ICOinvestor in bitcointalk forum who will see the signature of a user and they will click the link of the ico. It was a big help to expose their project or ICO to the investor.
Yes, it is one of the most effective ones in order to get awareness about the project, that's why many companies will allocate higher pools for the signature campaign because there are many investors in Bitcointalk forum, to get awareness about the project.
